SPECIFICATION forming part of Letters Patent No. 352,833, dated November 16, 1886.

Serial No. 187,530. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL D. Mom, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain Improvements in Liquid-Elevating Apparatuses, of which the following is a specification.

My invention relates to that class of apparatus especially adapted to city houses where the head or pressure of the water is notsufficient to raise it to the upper floors. It may,

sired to raise a portion of the water supplied above the level of the head or the level corre sponding to the pressure in the service-pipe.

My invention will be best understood by reference to the accompanying drawings, wherein Figure 1 is a sectional elevation showing my apparatus in a simple form as applied to a house of four floors, Where the normal pressure or head will lift the water nearly to the third floor. Fig. 2 is a detached sectional view of the two-way cock I usually employ to con- 'trol the supply of water to the primary reservoir in the'basement. Fig. 3 illustrates anautomatic float device for operating the cock of the primary reservoir. Fig. 4 illustrates the application of my invention toa house of seven floors. Figs. 5, 6, 7, and 8 are views illustrating a float device for use in the primary res ervoir shown in Fig. 4, and also a modification of the device for operating the two-way cock" of the primary reservoir.

All of the above mechanism will be fully described hereinafter.

Referring first to Figs. 1 and 2, let A repre sent a house of four floors, the third and fourth floors of which are to be supplied with water through the medium of my apparatus. B represents the head or level of water in the supply-reservoir; O, the street-main, and D the service-'pipeleading from the main to the house. All of the above may be arranged as usual.

raise the water quite to the third floor. E is the tight primary reservoir, placed in the basement and connected to the service pipe D through the-two-way cook a, (seen best in Fig. 2,) which is an enlarged horizontal section in the plane of the axis of the service-pipe. When the plug of cock a is turned, as in Fig. 2, the reservoir is open to the service-pipe and the water enters the reservoir and compresses the air inthe upper part of the same to a tension corresponding to the pressure in the servicepipe, as will be well understood. When it is desired to draw water in the basement for domesti'c use, the plug of cook a is turned. This shuts off the service-pipefrom the reservoir andopens the passage from the outlet-nozzle of the cock to the reservoir, and the water flows therefrom. The construction and operation of the two-way cock of this character is too well known to require any more minute description. This reservoir E may be provided with an ordinary glass-tube gage, b, to show at all times the level of the water therein.

G is thelightsecondary reservoir, placed on the second floor and a little below the normal head B, so that water from the main will rise into it. This reservoir is connected to the service-pipe D by a pipe, D, which enters the reservoir G at its bottom. A check-valve, c, prevents any water from flowing back from reservoir G through pipe D. An air-pipe, H, leads from the air-space d in the upper part of reservoir E to reservoir G. p I is a pipe leading from the lower part of reservoir G to a terminal res'ervoir', J, placed in the upper story and above the highest level to which water is supplied. In the lower end of pipe I is a this pipe from flowing back into reservoir G.

'In order to prevent, under normal conditions,

any compression of air in the terminal reser- 'voir J, I provide this reservoir with an airoutlet, f, and in order to prevent any overflow of water at this outlet under abnormal conditions I provide a valve, 9, to close this air-outlet, and a float, h, to raise this valve to its seat when the water rises in reservoir J above a predetermined point. Pipesi and j fourth floors, respectively, and pipes k and Z from pipe D supply water to the first and second floors, respectively.

The operation is as follows: When the Water is turned on-from the street-main O to the primary reservoir E, it rises in said reservoir and forces the air from its upper part, d,

from pipe I, supply water to the third and through pipe H, into the secondary reservoir G. This latter reservoir being always open to the main, the water will fill it under ordinary conditions; but when the air from reservoir E is forced into reservoir G it will produce a pressure on the water therein nearly equal to the pressure in the main, and this pressure will force the water from reservoir G up through pipe I to the terminal reservoir J. The amount of water lifted to reservoir J from reservoir G will depend. of course, on the displacement in reservoir E. This latter reservoir being now full, no further action will take place until the cook a is turned and water is drawn off therefrom. It will be observed that water cannot be drawn directly from the service-pipe through cook a, but all water drawn through this cock must be taken from the reservoir E. Consequently the natural demand for water in the basement will necessarily deplete reservoir E. When water is drawn from this reservoir, the air from reservoir G flows back into the air-space (1, pressure is removed from G, andthe water from pipe Dflows into it, tending to establish an equilibrium therein. The water from reservoir J and pipe I cannot flow back into reservoir G by reason of checkvalve 6. Now, when the flow of water from reservoir E is out oh by turning cook a, the water from the main again rushes into said reservoir, forces the air therefrom into reservoir G, and this forces the water from said reservoir up to the terminal reservoir J, as before stated. Thus the drawing off from the primary reservoir E of water for domestic use serves to raise water to the floors above the normal head B. The check-valve c in reservoir G prevents the water from being drawn from said reservoir for any service below it. Should there be no consumption of water on the third and fourth floors for a considerable time, and an excessive consumption forthe primary reservoir, thetendency would be to overflow theterminal reservoir J. This overflow will be prevented by the closing of outlet f. When this outlet is closed and the tension of air in reservoir J equals the tension in the reservoirs E and G, no more water can rise above the check-valve e. Where it is not desirable to rely upon the natural consumption of water from the primary reservoir, or where the consumption on the upper floors is greater than will. usually be supplied where the natural consumption from the said reservoir is relied on, I use an automatic device for actuating cock (1, whereby the water from the primary reservoir is drawn oft into the wastepipe. Such a device is illustrated in Fig. 3, which Iwill now describe.

E is the primary reservoir, D is the servicepipe, and a is the two-way cock. In this con: struction the pipe D enters the reservoir, and cook a is located in the latter. D is a pipe through which the water flows from the reservoir to the waste-pipe or for consumption, as may be desired. a is a two-way cock whereby water may be drawn from the reservoir E by pipe D or from the service-pipe by way of branch pipe D, as may be required. As this cook a is shown set in Fig. 3 it cuts off both pipes D and D. We will suppose it is desired that the apparatus shall operate automatically and Waste from reservoir E, and that cook a is so turned as to permit the water to flow from pipe D" through the port in said cock. K is a float in reservoir E, secured to an arm, in, hinged to the reservoir-wall at a. This arm is connected to an arm, 0, on the plug of cock a by a rod, 19. When this float falls, (as seen in Fig. 3,) it opens cook a to the servicepipe D, so as to admit water to the reservoir E from the main. L is an upper detent-float attachedto an arm, q,which is hinged at r. This arm g has a catch, 8, which takes over a stud, t, on the arm of float K, and prevents the latter from rising, except under certain conditions, hereinafter set forth. I M is a lower detentfloat attached to the end of an arm, a, hinged at 12. To this arm a is coupled a verticallyarranged rod, w, which is coupled at its upper part to a link, :0, and is provided at its upper end with a 'springlatch, y. When the water rises in reservoir E, it first submerges float K, but cannot lift it, by reason of catch 8. When, however, it rises high enough to raise float L, this acts to disengage catch 8 from stud t. Float K is released and rises suddenly. This movement rotates the plug of cook a a quarter-way round, shuts off the water from the main, and opens pipe D to the reservoir. The water now flows out of reservoirEthrough pipe D and cook a; but float K cannot descend by reason of the beveled toe 2 on it catching on the top of spring-latch y. Vhen the water falls low enough to uncover float M, this float descends, and by its downward movement.

draws latch y from under toe z. This permits float K to fall suddenly and shift the plug of cock (1 again to the first position seen in Fig. 3. It may be well to state that float Mregains the position seen in Fig. 3 as soon as the water rises high enough to buoy it up, and that when float K rises suddenly the toe z wipes over spring-latch 1 by reason of the yielding character of the latter. When cook a stands as shown in Fig. 3, the operation ,of the apparatus necessarily ceases. When cock astands so as to cut ofi the outflow of water from reservoir E by way of pipe D, water may be drawn at cook a through branch pipe D.

Figs. 4 to 8 0f thedrawings illustrate a further extension of the application of the principle of my apparatus to the elevation of the water to higher levels bysteps and automatically.

Fig. 4 showsa building, A, of several floors, the normal head B being sufficient (as in Fig. 1) to raise the water nearly to the third floor. The primary reservoir E is substantially the same as reservoir E, (seen in Fig. 1,) and the secondary and terminal reservoirs G and J are thesame as those before described. I intro-' duce in this arrangement, however, two additional reservoirs,G and G, on the fourthand sixth floors, respectively, which partake of the character of the secondary reservoir G and the terminal reservoir J. They partake of the character of the reservoir G in that they are connected, respectively, by air-pipes H and H with the primary reservoirE, and serve to receive water from below and force it to a higher level, and they partake of the character of the terminal reservoir J in that they receive water from a reservoir below and not from the service-pipe direct, and have each a valve-controlled air outlet to prevent compression of air when they are receiving water.

As I have said, each of the reservoirs GG G is connected by a separate air-pipe with the primary reservoir E. When the latter reservoir is empty, or nearly so, and the cock a is turned to admit water to said reservoir, the air is first forced into reservoir G through pipe H, the other air-pipes, H H, being closed.

' When the displacement in reservoirEis sufficient to force all of the water from reservoir G up to the reservoir G, then the-air-pipe H is closed and air-pipe H opened. When the displacement in reservoir E is sufficient also to force all the water from reservoir G up to reservoir G, then the air-pipe H is closed and air-pipe H opened, and the continued displacement in reservoir E serves to force the water from reservoir G up into the terminal reservoir J ,which may supply the upper floors through a pipe, N, and its branches. In order that the air may'escape from the upper part of the reservoirs G and G, each of these is provided with an air-outlet, f, provided with a readily-elosable valve, which stands normally alittle off its seat,so as to permit the air to flow out under the gradual and gentle pressure caused by the incoming water. The mouth of the air-pipe (H in reservoir G) from reservoir E is arranged just behind this valve 9, and when the air-pipe H is closed and this airpipe is opened the first incoming jet closes valve 9 instantly, and the pressure in the res} ervoir will keep it closed until the'tension is afterward relieved. I may say, by way of ex.- planation, that reservoirs G and G are constructed and provided alike, and I have only shown one of them in section in Fig. 4. In ordeer that the primary reservoir E may have sufficient displacement to operate all of the reservoirs G, G, and G, .I give it a capacity equal to them all, and in order that the airpipes H, H, and H may be opened and closed in proper succession, I provide the primary reservoir E with a suitable automatic mechanism to effect this, one form of which is illustrated in Figs. 5, 6, 7, and 8. Fig. 5 also shows a mechanism for opening and closing in alternate order the two-way cock a.

In Fig. 5, E is the primary reservoirin vertical section. 'The air-pipe H extends down into the reservoir about. two thirds of the depth. The air-pipe H extends down about one-third of its depth, and the air-pipe H terminates near the top of the reservoir. On the lowerend of pipe H is an ordinary cock, I), the axis of its plug being horizontal. A float,

' B, is connected by its arm to the plug of this cock. When this floatfalls, the cock is opened, and when it rises to a horizontal position the cock is closed. On the lower ends of pipes H and H are fitted, respectively, cocks b and b,

of like construction. This cockis illustrated in detail in Figs. 6 and 7, the former being a cross-section on the center, and the latter a side elevation. The cock has two ported plugs, one within the other, and each capable of rotation independently of the other.

Referring to Fig. 6, H is the air-pipe. c is the passage therein. d is the shell of the cock. e is the tubular outer plug. 6 is its crossport. h is the inner plug, and h is its crossport. It will be obvious that the passage of water through the cock may be stopped by turning either plug, and that when the port in either is set to coincide with the passage 0 the passage in the other must also be brought into coincidence before the cock will be opened. The float B is connected by its arm to the inner plug, h, of the cock b, and float B is connected by its arm to the inner plug of cock 1/. To the outer cylindrical plug, e, of cock I is fitted an arm, 2",which is connected by a rod, j, with the arm of float B. To the outer cylindrical plug of cock b is fixed an arm, 2", which is connected by a rod with the arm of float B.

The operation is as follows: Whenthe reservoir E is empty, and the floats B B Bhang suspendedas weights, cock b is open and cooks b and b are closed. The entering water forces air out of the reservoir through pipe H to reservoir G, until it rises highenough to lift float B and close cock I); but float B in rising acts through rod j and arm 1' to open cock b. When floats B and Bstandor hang as in Fig. 5, the plugs in cocks I) stand as in Fig. 6, port h being in coincidence with passage 0,- but port e is out of coincidence, and the cock is still closed. The riseofl-float B turns plug e until its port 6 is in coincidence with port h. The rising water now forces the air from reservoir E to reservoir G, through openv cock I) and pipe H. When the water rises high enough, float B lifts, closes cock b,and, acting through rod 7' and aunt, opens cock b, so that air may pass from reservoir E to reservoir G through pipe H. The water continues to rise until float B is raised high enough to close cock 1/. When the water is drawn from reservoir E, the movements and operations are reversed. The fall of float B' closes cock b and opens cock I). The fall of float B closes cock b and opens cock 6.

I will now explain the operation of the electromechanical device illustrated in Fig. 5, and designed to effect the filling andemptying of the reservoir E automatically. This is a means for accomplishing the same results as IIO the float device seen in Fig. 3, and although I do not claim it I have found it more convenient for illustration, in connection with the float mechanism shown in Fig. 5, than the device shown in Fig. 3 would be.-

0 is a circuit breaking and closing device of any kind, arranged at the lower part of the reservoir E and adapted to close an electric circuit by the fall of a float, O, and to break said circuit by the rise of said float. P is another circuit hrcaking and closing device, arranged at the upper part of reservoir E and adapted to close an electric circuit by the rise of a float, P, and to break said circuit by the fall of said float. Q is a battery, one pole of which is connected by conductors k and k, respectively, with the contacts Z and Z of the circuit breaking and closing devices I? and O. The other pole of the battery is connected with the other contacts m, and m", of the devices]? and 0, respectively, through the coils of electro-magnets It and It, their armature-levers n and 11", respectively, and the wires 0' 0 0' p p 19', as clearly shown. The armaturelevers contact at q when thecircuits are broken at both 0 and P. On the end of armaturelever n is a latch'hook, 9", which is arranged to catch one of the four arms 3 s on the axis t of the cook a. On this axis is also fixed a drum or barrel, it, on which is wound a rope or chain, 12, to which is attached a weight," S.

The operation is as follows: As shown in Fig. 5, the water is rising in reservoir E, cock a being open to the main. The circuits are broken at O and P. "When the water rises to the top of reservoir E, float I rises and closes the break in the circuit at P. The current flows through both coils of magnets R It. Both'of these magnets being vitalized, they will attract their armatures and lift their respective armaturelevers n and n. The rise of lever n frees the catch 1' from the arm 8, and allows weight S to rotate axis t of cock a; but the movement of the levers a it instantly breaks the circuit at q, and this cuts out magnet R and permits its armature-lever n to be retracted in time for hook r to catch on the next succeeding arm 8 and stop the rotation of the axis t. Thus the cook a is permitted to make but onefourth of a revolution, which is sufficient to cut the reservoir E off from the service-pipe and open it to the waste or consumption outlet. The circuit remains'closed at Puntil the water falls, and while the circuit is thus closed magnet R remains vitalized. When thewater has wasted from the reservoir and float O has fallen low enough to close the circuit at O, the current will flow through the coils of magnets R and R, their armatures will be attracted and catch 1' will release the arm 8 and allow the axis of cock to to make another quarter-revolution, thus cutting off the waste and opening the reservoir again to the service-pipe. The

weight S may be wound up at intervals by simplyrotating the axis t of the cock backward; or the barrel u might be ratcheted on the spindle or axis t in a well-known way.

I may say by way of explanation, that the illustration of this electro mechanical device in Fig. 5 is somewhat in the nature of an explanatory diagram drawn at one side of the primary reservoir. The spindle or axis 15 of cook a alone is shown. It will be obvious that this axis t may represent merely a shaft from which the plug of cook a can be rotated by any of the well-known mechanical devices used for such purposes-as a belt, for example. This diagram shows axis 15 arranged in a horizontal position; but this is only for convenience of illustration. I may also add that I have shown the device 0 placed at the bottom of the reservoir at the point where float O is necessarily placed; but this is only for convenience of illustration. It would be better to place the pairs of contacts Z m and l" m, above the highest water-level, and connect them to the floats by rods. This will be readily understood.

Fig. 8 is a sectional plan designed to illustrat-e the construction and arrangement of a branch pipe, T, and a globe-valve, U, therein, whereby water may be drawn from the servicepipe for consumption when the cock a is turned so as to admit water to the primary reservoir from the service-pipe.

It will be obvious that the electromechanical device illustrated in Fig. 5 may be substituted for the float deviceillustrated in Fig. 3, and the latter device may also be used in the reservoir E of-Fig. 5, in lieu of the electro-inechanical device,in case room is provided for it.

My invention may be employed in any case where a liquid is to be raised above the level of its head, and it may be used to advantage at times in breweries, distilleries, &c. In such an application of my invention anyliquid-as beer, for example may be supplied to the secondary reservoir G, to be raised above the level of the said reservoir, and water from the .main be supplied to the primary reservoir and drawn or wasted therefrom. This will produce the same effect on the liquid in reservoir G as if said liquid was water from the main. To effect this application of the apparatus illustrated in Fig. 1, it is only necessary that pipe D shall be arranged to supply a liquid to reservoir G from some other source than the service-pipe D-as, for example, from a vat on the second floor. This change will not require separate illustration. It will be observed, also, that the choice of self-acting check valves 0 and e and a two-way cock, (1, is designed to render the operation as nearly independent ot the domestic or employ as possibl'e.

I am aware of the patent of John McOloskey, No. 127,624, of June 4,1872, and I wish it understood that I do not claim what is therein shown.

Having thus described my invention, I claim- 1; The combination, with the primary reservoir E and its two-Way cock at, of the float K, connected with an arm of the cock-plug,

and latch devices, substantially as described, for detaining said float against rising and falling until the liquid in the reservoir has reached the predetermined levels, substantially as set forth.
